revset: simplify orderedlazyset creation in spanset method We can simply use the `self.isascending` value instead of more complex if/else clause. This get the code simpler. Benchmarks show no performances harmed in the process.

revset: use spanset.isdescending in multiple simple places We call the method directly instead of duplicating checks. Benchmarks show no performances harmed in the process.

revset: wider definition of ascending and descending for spanset Before this patches, empty spanset were seen as neither ascending nor descending. This is mathematically wrong and create some edges case. We put `isascending` and `isdescending` back on track so we can use them to simplify some of the spanset code. Benchmarks show no performances harmed in the process.

annotate: port to generic templater enabled by hidden -T option If the selected formatter is other than plainformatter, raw data are passed to the formatter. In this case, it isn't necessary (and not possible) to calculate column widths. Field names are substituted to be the same as "log" command. There are a few limitations: - "binary file" message is not included in formatted output. - no data structure for multiple files. all lines are packed to single list.

annotate: split functions to get data without applying text formatting This prepares for porting to generic templater API, where raw data should be passed to the formatter. makefunc() is necessary to build closure in list comprehension.

annotate: remove unused variable in calculation of column widths

annotate: build format string separately from annotation data This prepares for porting to generic templater API. Note that we cannot use '%*s' to pad white spaces because it doesn't take into account character widths, as described in 4f5a6df2af92.

formatter: convert float value to json It will be used to encode ctx.date().

formatter: have jsonformatter accept tuple as value This is necessary for "annotate" to encode ctx.date() in the same manner as jsonchangeset printer. It doesn't support list object because keeping mutable object in _item could be a source of hidden bugs. Also, I can't think of the use case.

formatter: extract function that encode values to json string This is the stub for tuple support, which will be used to encode ctx.date() in the same manner as jsonchangeset printer.

contrib/synthrepo: pass options to ctx.diff as kwargs, not a dict

contrib/synthrepo: only generate 2 parents if model contains merges If `hg analyze` is run on a revision set which contains no merges, then `hg synthesize` will raise IndexError trying to select from p2distance, which will be empty.

convert: add support to find git copies from all files in the working copy I couldn't think of a better name for this option, so I stole the Git one in the hope that anyone converting a Git repo knows what it means.

convert: add support to detect git renames and copies Git is fairly unique among VCSes in that it doesn't record copies and renames, instead choosing to detect them on the fly. Since Mercurial expects copies and renames to be recorded, it can be valuable to preserve this history while converting a Git repository to Mercurial. This patch adds a new convert option, called 'convert.git.similarity', which determines how similar files must be to be treated as renames or copies.

convert: for git, factor out code to add entries to a separate function We're going to call this for multiple files in one iteration in upcoming patches.

convert: for git's getchanges, always split entry line into components We always need to know whether the entry is a rename or copy, so split it up unconditionally.

convert: for git's getchanges, use explicit index for iteration Upcoming patches will add support for copies and renames, for which we'll need to access multiple lines of the difftree output at once.

convert: add initial docs for git sources Upcoming patches will add config options for git sources. This patch adds a place to document them.

color: document that changeset phases have labels It's very useful to be able to colourise csets according to their phases. There was no indication anywhere in the docs that this is possible. We use e.g. `changeset.secret = ` instead of `changeset.secret ='none'`, because otherwise this is a BC: it would nullify the effects given to log.changeset label that usually surrounds the changeset.{phase} labels. Specifying the label without any effect instead of 'none' is a true no-op change and purely documentation.

color: change the debug output format Before, the format was label(labeled text) # single label [label1 label2](labeled text) # multiple Now, it's [labels|labeled text] ..which should make things a bit more clear.

color: enable debug option to show labels This is a debug option for showing labels. This can be helpful for knowing which labels are available for colouring or to see the output when defining your own templates. A couple of tests are included.

color: document that labels are used for colorizing text It is a deeply hidden secret that it's possible to colorise so many things with so many different labels. This is an attempt to document this. The text is a bit long, but it seems as short as can be while documenting everything. Perhaps it should be hidden under a --verbose option.

contrib: add OS X p4merge to mergetools.hgrc

patch: enable diff.tab markup for the color extension The following patch splits up changed lines along tabs (using re.findall), and gives them a "diff.tab" label. This can be used by the color extension for colorising tabs, like it does right now with trailing whitespace. I also provide corresponding tests.

dirstate: copyedit exception for no beginparentchange call

revsetbenchmarks: add an additional roots() benchmark The existing roots(x - y) revset only considered the most recent 100 revisions. This was a good start. But expanding it to the full history of the repository can dramatically increase execution time and thus constitutes a useful benchmark.

mq: examine "pushable" of already applied patch correctly Before this patch, "hg qselect" with --pop/--reapply may pop patches unexpectedly, even when all of patches applied before "qselect" are still pushable. Strictly speaking about the condition of this issue: - before "qselect" - there are N applied patches - the index of the guarded patch X in the series is less than N - after "qselect" - X is still guarded, and - all of applied patched are still pushable In the case above, "hg qselect" should keep current status, but it actually tries to pop patches because of X. The index in "the series" should be used to examine "pushable" of a patch by "mq.pushablek()", but the index in "applied patches" is used, and this may cause unexpected examination of guarded patch. To examine "pushable" of already applied patch correctly, this patch uses "mq.applied[i].name": "pushable" is the function introduced by the previous patch, and it returns "mq.pushable(mq.applied[i].name)[0]".
